Attempting Trench Construction Technology of Ultra-deep Diaphragm Wall

Diaphragm wall construction technology is widely applied in the harbor,subway,building and other large deep foundation engineering.The existing trench construction method whether could satisfy the local geological conditions with rich water,soft soil and thick sand layer is an important problem to be paid attention and settled.The theory related to attempting trench construction technology of ultra-deep diaphragm wall is systematically analyzed and used to actual construction,and the good results have been obtained.
